Description
Technical field
The present invention relates to a kind of packaged type unregulated power and drive Control device of liquid cooling and liquid cooling method, more particularly, relate to a kind of air force driven cooling devices and air force driving liquid cooling method that is applicable in the volatilizable cryogenic liquid storage process.
Background technology
Down-hole survival capsule is also named " down-hole refuge "; Its function is: after catastrophes such as permeable, fire, gas and dust explosion, water damage take place in the down-hole; Best-effort path hindered with other impracticable situation of escaping under, for timely evacuator person provides the confined space of a safety.According to the investigation of countries in the world to mine accident; In accidents such as fire, blasts the dead miner that comes to harm of on-the-spot moment being taken place only accounts for the part of accident casualty number; Have quite a few miner all to be because at mine timely gug or flee from high temperature, toxic and harmful scene after permeable or fire, the blast, cause drowning, suffocate or be poisoned to death.Therefore; Each state is all building mine refuge underground chamber and the mining survival capsule of development energetically, so that the miner that can't in time withdraw after having an accident for mine provides the confined space of a safety, externally can resist blast impulse, high-temperature flue gas; Isolated toxic and harmful; Internally can remove toxic and harmful, win long life span for stranded miner provides oxygen, food and water.Military affairs medical aspect, a lot of occasions need place the wounded closed environment such as hyperbaric oxygen chamber to treat, and need control and regulate carrying out parameters such as temperature humidity in the cabin equally, and Medical Devices are cooled off.Because a situation arises in mine disaster down, the down-hole has not possessed the ability of supply of electric power, and the electric power storage ability of battery is also limited; And because the restriction of safe coal authentication makes the refrigeration air-conditioner of big electric current use possibility hardly.Aspect military first aid,, be difficult to be applied to military first aid equipment thereby make conventional electric power drive refrigerating method because the uncertainty in battlefield and the variation of situation can't guarantee supply of electric power more.Therefore, a large amount of mine survival capsule and military first aid equipment all is to carry out refrigeration air-conditioner and apparatus cools with liquid CO 2 etc.
Liquid working substances such as liquid CO 2 are applied to the refrigeration air-conditioner of survival capsule and military first aid equipment, make these equipments break away from the dependence for electric power facility, have increased the practicality of escape capsule of mine, have improved the mobility of military first aid equipment.But although this liquid refrigerating equipment has solved the problem of expense electricity refrigeration, because the variation of environment temperature, efficient reduces.For mine enterprise, because survival capsule will be equipped in the down-hole throughout the year, but downhole temperature has surpassed the critical point of carbon dioxide much at more than 30 degree, causes the liquid CO 2 evaporation, and pressure rises; In case reach safe threshold values, safety valve just can be opened, and bleeds off partial CO 2, and the liquid CO 2 that directly causes storing reduces, and system's refrigerating capacity descends.For the military first aid equipment, environment is more abominable, both possibly be arranged in desert edge, also possibly be arranged in southern height and thermally distinguish, and the loss of liquid CO 2 is just more.
Existing mine and battlefield carbon dioxide liquid storing technology do not solve the problem of liquid evaporating loss basically, make efficiency of storage descend.
Summary of the invention
The present invention is directed to deficiency of the prior art, provide a kind of packaged type unregulated power to drive Control device of liquid cooling and liquid cooling method, is power with compressed air, realizes the cooling to storaging liquid, improves the efficiency of storage of liquid working substance, reduces evaporating loss.
One of the object of the invention is to provide a kind of packaged type unregulated power of volatile liquid cooling that is applicable to drive Control device of liquid cooling; Comprise cooling unit, cryogenic liquid storage unit and control module, be connected through refrigerator pipe between said cooling unit and the cryogenic liquid storage unit.
Cooling unit of the present invention comprises stable-pressure device, dry filter device and turbo-expander, connects successively through tube connector between each device.Cooling unit is assembled in the housing, and housing insulation back constitutes ice chest, mobile device is housed below the housing, can move.Cooling unit has air inlet, give vent to anger two air hose interfaces and signal wire interface.Wherein the air inlet pipe interface connects air source, and the escape pipe interface connects cryogenic liquid storage tank liquid chiller cool air inlet and takes over.Holding wire connects the cryogenic liquid storage tank fluid temperature sensor.
Stable-pressure device according to the invention is made up of Pressure-stabilizing pressure reducing valve, high pressure gauge and surge tank, and the Pressure-stabilizing pressure reducing valve is high pressure air reducing and be stabilized to the operating pressure of turbo-expander, sends into surge tank; Surge tank is used for reducing the air pressure fluctuation, guarantees that the air pressure of turbo-expander inlet is suitable, and it is little to fluctuate, and is stabilized in design conditions.Those skilled in the art can know other can realize high pressure air reducing and the device that is stabilized to specified pressure all can be used for the present invention, Pressure-stabilizing pressure reducing valve, high pressure gauge and surge tank structure are preferred here, and unrestricted.
Dry filter device according to the invention mainly is made up of air filter and built-in desiccant.The preferred dry filter device of the present invention is also unrestricted, and other can realize the device of the purge drying function of air all can be used for embodiment of the present invention.The air that this device is come to surge tank purifies and dry preliminary treatment, prevents that the air that gets into turbo-expander from carrying impurity and steam secretly, causes the impeller damage.
Turbo-expander according to the invention is installed in the electromagnetic valve back; The air inlet port of turbo-expander expansion impeller connects electromagnetic valve outlet through tube connector; The outlet of expansion impeller connects the escape pipe of cooling unit, and inserts liquid chiller through the tube connector of cooling unit and cryogenic liquid storage tank.Said turbo-expander mainly contains expansion impeller and compositions such as spiral case, axle, bearing, braking supercharging impeller and spiral case.
